HAREOW Feit ATTACHMENT To SEED-mains.V j

f BeV it known that I, WALTER ARNOLD DEUTSCHER, a subject of the King of Great Britain and Ireland, and a resident of the post-town of vlVIurtoa, in the countyv of Borung, State of Victori,a,. Commonwealth of Australia, whose post-oliice addressis Marina street, in the said ypost-town ofMurtoa,l1ave invented certain new and useful Improvements inandConnected with Harrows for .Attachment to Seed-Drills, .of

whichthe following is a specication.

This invention relatesto `the harrowing of a field after the.I sowing of seed. Usually adrill having a series of hoes is employed `for sowing and isprovided with a lateral `footboard. subsequently followed by a separate har-row. This involvespeXtra horses andadditional labor. The' driver, when a separate harrow is employed, must also walk' behind the same. The advantages, however, of'immediately harrowing a sown field are well recogi nized, Ythe seed then being proteetedfrom birds andmice. Trailing chains or the atever, usually either ineficient or vmaterially increase the draft. l

The obj ect-of this invention is to provide a harrow which ,-mayA be attached to and drawn by the drill'without alteration thereto. and without materially yincreasing the draft thereof. The invention is cheap, simple, light and easily and quickly attached the like. Further, it is disposed in a protected position, does not interfere with free access to the drill when charging the seed box thereof, moves withthe hoes when they vare moved from the soil'and always lmoves with facility over rough and uneven ground without leaving portions thereof. unhar i are therel'nvy'united.l VIt is'y not considered vnec- Qessary to provide' stays between the intermey diate front and'backtine supports or bars.

draw strap/engaging a back tine-support fTheinventionis attached Vto a seed'drill f lhaving alseries of hoes 2 projecting from each of which is lusually an arm 3 connected with` controlling links andlevers not concerned lwith the present-invention. Behind the hoes is a footboa1-d4eXtending from one side of the machine tol the other. Dis.-

' posedbelow' the footboar'd is aharrow con-1v sisting'of a sectional front tine support 4or` bar. This-isv preferably divided4 into three (more or less) sections thereby forming two end bars 5 and anintermediate bar 6. The

pivot pins 7 tothe ends lof the rintermediate bar 6; Depending from eachbar or section isa vseries of front tines 8."

`inner ends of the two bars 5 are pivoted by l Behind the front tine support or bary is yav Y sectional back tine support or bar also consistingof'three (moreorless) sections and thereby forming two end bars 9 and an intermediate bar 10. "The inner ends of the two ends bars 9 are pivoted by pivot 'pins 11 to the ends of the intermediate @bar 10.` Dependingvfrom each of the bars or sections is a. series of back tines 12.Y `Thefront and back tines are not' in line, the back tines being centrally disposedfinfrelation to Hthe spaces between thefront'tinesi' In plan the tines are therefore'zig-zagged. p

v Extending between and'securedto each front end support or bar pand each back endy support or bar 9 are twotmore or less) diagonalV cross stays `13 secured i to each other Iat their points'of interse'ctionby pins ll or` the like. .The'frontyand back Vtine supports If desired the diagonal'cross stays-may be L i adjustablyse'cured Vto the tine supports so V'that the distancebetween the front and back tine supports may be adjusted, if desired, by variation of the position of the stays with regard' t'o the supports. It is obvious that l the harrow may be readily folded as seen in lief With theforegoing anduniting the harfl: i

row to the hoes of the seed drill are three (more or less) draw straps. Each strap consists of a bow having two inclined legs 16 formed in each of which is a series of adjusting holes 17 to accommodate a cross y bow 15 is a horizontal leg 19 having an up and over-turned end 20. rfhe horizontal legs 19 may pass either over or under the sectional front tine support, the over-turned ends 20 of the said legs 19 engaging the sectional back tine support.

Retaining each of the draw straps to the harrow is a clamp. Each clamp is disposed above the ends of the horizontal legs 19 of the strap and consists of a body portion 21 resting upon the back tine support. 'Formed in the body portion is a bolt hole 22. Integral with the body portion 21 at each side of the same is an out-turned' leg 23 having an underturned end 24. The outturned legs 23 are disposed above the herizontal legs 19 ofthe draw straps the underturned ends 24E passing beneath the said horizontal legs 19 which are thus prevented from spreading or moving apart during operation of the harrow. Beneath each clamp and beneath the back tine support is a holding plate 25 having an rip-turned front edge 26 engaging the front edge of the said back tine support. Passing through the holding plate 25 is a holding bolt 27 which also passes through the bolt hole 22 in the body portion 21 of the clamp above it.

Instead of retaining the draw straps to the harrow by the clamps described a single 'clamping plate could be disposed beneath the horizontal legs of each strap and be retained to the back tine support by a holding bolt or bolts therebyclamping the said legs to the said support.

In a modification the clamp described is dispensed with, a U shaped clamp 28 engaging the horizontal legs 19 of each draw strap and passing diagonally beneath the sectional back tine support or bar, as seen in Fig. 6. Above the supporter bar is adiagonally disposed holding plate 29.

.l/Vith this invention as the drill moves forward over the lieldand sows the seed the harrow is drawn immediatelyafter the saidv drill. Ihe driver stands upon the `footboard 4f of the drill which being disposed above and behind the harrow protects the same and prevents the driver from stepping down thereupon inadvertently. rIhe harrow by reason of its pivoted sections may move freely over and always engages with uneven ground. rI`he number' of sections employed may'vary. The pivoted sections also yprovide for the harrow being folded. The bows 15 of the draw straps of the harrow loosely embrace the hose of the drill in order that the said harrow may rise'vertically in relation to the hoes 2 the amount of travel being governed by the position of the adjustable cross pins 18 across the inclined legs 16 of the said bows 15. Should it be desired to remove the harrow it is only necessary to remove the holding bolts 27 from the clamps when the harrow may be immediately removed from the draw straps. Removal o-f the clamps 28 when employed is apparent. The draw straps may remain in position upon the hoes 2 but should it be desired to remove the said draw straps it is only necessary to withdraw the cross pins 18 thereof.

Having now described my invention, what I lclaim as new and desire to secure by Letters Patent is 1.

5. Improvements in and connected with harrows for attachment. to seed drills, consisting in the combination with a hoe drill of a harrow having a front tine support and a back tine support each consisting of a plurality of folding pivoted sections, a series of tines carried by each support, said tine's being zig-zagged in relation to each other, means for uniting the front and back tine supports, and means for attaching the harrow to the drill hoes.
